Serial No. 496,695.

The object of this invention is to provide a resilient socket member ofa snap fastener couple, with a collet encircling the spring elements insuch way as to shield these elements against destruction of the snapaction in the event of the article on which the socket is used beingdropped, as on a floor, and stepped on, and whichwill take anyunusualblow,

and which also will protect the socket when the flange, to impartresilience to the socket collet.

member, and having a collet encircling and closed about the flange insuch way as to permit resilient action in connecting the socket with acomplemental stud member and disconnecting it therefrom, as I willproceed now to explain more fully and finally claim.

In the accompanying drawings illustrating the invention, in the severalfigures of which like parts are similarly designated, Figure 1 is a topplan view; Fig. 2 is a bottom plan view, and Fig. 3 is a verticalsection of the spring member of the socket. Fig. i is a top plan view;Fig. 5 is a bottom plan view, and Fig. 6 is a vertical cross section ofthe Fig. 7 is a vertical section of the spring element and colletassembled. Fig. 8 is a top plan view; Fig. 9 is a bottom plan view, andFig. 10 is a vertical section of a cap for attaching the colleted springelement to an object and at the same time presenting a finish to theattached parts. Fig. 11 is a vertical section of the parts attached to apiece of material.

The spring element, shown detached in Figs. 1, 2 and 3, may be of anyusual or approved construction, in which there is a barrel 1,terminating in a laterally projecting flange 2, the barrel being slittedpartway of its length, as at 3, and these slits extending entirelythrough the flange, as indicated at i, so as to impart resilience to thedevice.

The juncture of the barrel and flange has an oifstanding head 5 whichforms a constricted spring neck adapted to engage the complementalportion of the stud member (not shown) of the snap fastener couple,which stud member may be of any usual or approved construction.

The collet is composed of a top portion 6 provided with a hole 7 of adiameter larger than that of the barrel 1 of the spring element and alsois provided with a circumferential flange 8. I

As shown in Fig. 7, the collet when applied to the flange 2 encirclessaid flange, and its top 6 and flange 8 are closed about the said flange2 above and below, respectively, in such manner as to be entirely freefrom the bead 5. Thus the collet is arranged in floating engagement withthe flange 2 and allows suflicient space for the expansion of the springelement in the act of connecting and disconnecting the stud member.

The thus colleted spring element is applied to an article, indicated bythe part designated 9, Fig. 11, by inserting the barrel through thearticle and then closing the cap 10 over the barrel and mushrooming saidbarrel so as to afford a secure connection of the cap with the barrel.

This cap 10 may be of any approved construction, but the preferredconstruction, as shown in Figs. 8, 9 and 10, has the closed head 11 andthe inturned slitted back 12, which slitted back engages thebarrel'above the bead 5. I

When the parts are assembled as shown in Fig. 11, the collet takes upany strains placed upon the socket and thus prevents distortion. Thecollet, furthermore, in the case of any lateral pull or strain on thesocket in coupling it with the complemental stud member, supports thesocket member and thus prevents the undue pulling apart of the springportions of the socket and so obviates the distorting and spoiling forfuture use of the said socket.

The collet. furthermore, when closed around the flange of the socket,acts as a shield which prevents the impairment or deluu 7 especially tothe laundry wringer. Moreover,

' by the closed-in flange of the collet instead o of the socket andextendinginto close proxby this arrangement, any unusual blow orpressure upon the socket Wlll be taken up ofby the resilient memberitself.

I am aware that it is old toprovide a collet on a socket member by meansindependent of the stud-engaging springs; and I am also aware that it isold to apply a collet to the turned-out edges of the spring socket, theapplication of the collet serving to turn out and clinch such edges;and. I am also aware that it is old to provide a spring socket memherhaving a lateral flange to which is applied a binding ring having alower flange fitted beneath the oflset portion oi the flange of thesocket and lying approximately flush with the surface of the socketflange and its stud-engaging portion, from which construc tion my socketand collet difl'er in that the top portion of the collet overlying theflange of the socket extends into close relation to the barrel of thesocket and overlies the bead thereof while ,the lower portion of thecollet underlies the flange and extends well below the bead; and I amalso aware that it is old to apply a binder to a spring socket byplacing the open end of the binder on the bottom ofthe lateral flange ofthe socket and then placing a ring above such flange and closing downthe flange of the binder upon such ring, thus exposing the stud-engagingelement of the socket to potential danger from blows instead ofprotecting it as in my construction.
